Our assessment
The evidence shows that this product contains calcium, which is a mineral essential for bone health. However, the data we have is for the ingredient calcium, not specifically for the Isotonix Magnesium product. We cannot confirm the specific benefits of the delivery system or the product's overall formula based on the provided information. Our assessment is that while calcium is a well-studied nutrient, the specific claims for this product cannot be evaluated with the data available.
How it works
Calcium supports your body in two key ways. First, it is critical for bone mineralization, helping to build and maintain strong bone density. Second, it supports neuromuscular relaxation, meaning it helps your muscles relax and your nerves send signals properly [NIH ODS].
Safety profile
Data not available on side effects specific to this product. However, high calcium intakes might increase the risk of heart disease and prostate cancer [NIH ODS]. Very high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS]. The FDA has received a total of 592,059 adverse event reports for all products in their database, but this number is not specific to this product [FDA data].
Our recommendation
Because the data provided is for the ingredient calcium and not for this specific product, we cannot make a confident recommendation. You should consult with your healthcare provider before taking this supplement, especially if you take any of the medications listed above. If you do choose to take a calcium supplement, be aware of the potential risks and do not exceed the recommended intake without medical supervision [NIH ODS].
